1. Selection of Superheated Steam Flow Meter

The selection of superheated steam flow meters should comprehensively consider the pipe diameter, maximum temperature, maximum pressure, flow range, and measurement accuracy. Common types include vortex street, bend pipe, V-cone, and orifice plate. Among them, vortex street and bend pipe are more suitable for high temperature and high pressure scenarios, while orifice plate and V-cone are less commonly used due to accuracy and pressure loss issues. The specific selection suggestions are as follows:

1. Common types and characteristics: Vortex simplified code Qingjie flowmeter is suitable for scenarios where the pipeline is less than DN300 and the temperature is ≤ 450 ℃. It is necessary to adopt an integrated design of temperature and pressure compensation to ensure accurate measurement. According to user needs, integrated or split type instruments can be selected, and the instrument diameter can be determined based on the steam consumption of pipelines and equipment. The installation method is flexible (horizontal or vertical), but it needs to meet the requirements of the front and rear straight pipe sections, avoid pipeline vibration (shock absorption is required when the vibration is large), and pay attention to the impact of high temperature environment on the instrument. Outdoor installation requires protection. Bend flow meters are recommended for use in pipelines larger than DN300, especially suitable for high temperature and high pressure environments. Simple structure, minimal pressure loss, and good long-term stability. Although V-cone flowmeter can be used for steam measurement, its practical application is limited due to the large pressure loss and u

2. The core selection criteria are based on the pipeline diameter DN300 as the boundary point: vortex flowmeters are preferred for those smaller than DN300; It is recommended to choose a bent pipe flowmeter for sizes greater than DN300. The temperature and pressure of superheated steam are high (usually>saturated steam temperature), and there are large pressure fluctuations. Therefore, instruments that can withstand high temperature and high pressure should be selected (such as vortex flowmeters that need to support temperatures below 450 ℃). The flow range and accuracy are determined by selecting instruments that match the actual steam consumption range, in order to avoid increasing errors caused by long-term low flow operation. The integrated vortex flowmeter with temperature and pressure compensation can significantly improve the measurement accuracy. Prioritize safety and cost by choosing instruments with simple structures and high reliability (such as bend tube flow meters) to reduce maintenance risks. Taking into account the price of instruments, installation costs, and long-term operational stability.

III. Precautions for special scenarios Vibration and installation of vortex flowmeters are sensitive to vibration. If the pipeline vibration is large, shock absorbers should be installed or anti vibration instruments should be used instead.
